Thermoeconomic diagnosis of refrigeration systems is a pioneering approach to the diagnosis of malfunctions, which has been recently proven to achieve good performances for the detection of specific faults. Being an exergy-based diagnostic technique, its performance is influenced by the trends of exergy functions in the “design” and “abnormal” conditions. In this paper the sensitivity of perfor...

The optimization of the steam parameters heat recovery generators (HRSG) Combined Cycle Gas Turbines (CCGT) has become one important means to reduce power generation cost combined cycle units. Based on structural theory thermoeconomics, a thermoeconomic model for triple pressure reheat HRSG is established. Taking minimization system as objective, an algorithm based three factors and six levels ...

The concept of optimization operating and design parameters the regenerative air turbine cogeneration (RATC) system is proposed. To determine energy efficiency indicators this system, its thermodynamic analysis was performed. At same time, it shown that not correct to search for optimal such a only by indicators, modern thermoeconomic methods should be more actively involved in pre-design pract...

Low-temperature geothermal heat sources have the highest share of energy in world. Utilization these for and freshwater generation can play an important role meeting demands. To do so, this study aims to propose a novel trigeneration cycle powered by low-temperature sources. The proposed system, which is integration Kalina humidification-dehumidification (HDH) cycles, used electricity, heating,...

The organic Rankine cycle (ORC) has been widely studied to recover waste heat from internal combustion engines in commercial on-road vehicles. To achieve a cost-effective ORC, trade-off between factors such as costs, power outputs, back pressure, and weight needs be carefully worked out. However, the is still huge challenge engine recovery. In this study, thermoeconomic optimization study of ve...
